Medium & Low Voltage Soft Starters

Direct-on-line (DOL) starting of large industrial motors places heavy mechanical stress on shafts, couplings, gearboxes and driven equipment, while drawing inrush current several times the rated value straining the plant busbar and upstream protection. Across power, cement, metallurgy, petrochemical and water infrastructure, this repeated stress shortens equipment life and raises maintenance costs. The Lubi Electronics Soft Starter range HSD2000 for medium-voltage motors (3.3-11kV) and LSD100-B for low-voltage motors (200-460V) addresses these operational challenges with controlled voltage ramping, complete motor protection, and intelligent bypass control, extending asset life while reducing starting-related downtime and energy losses.
